You have to know when it is the end, and so many fighters never know when to quit. Hatton had taken some fearful beatings even when he won! Look at his face after the Tszyu fight! Hatton was never going to have a long lasting career well into his 30's and with weight fluctuating like it did then his body was always going to be susceptible. He was winning the fight until that body shot and he just couldn't absorb it. An easier opponent is just bollocks, if he had won then he would've been hailed as the comeback kid. It would've only delayed the inevitable next KO loss. Hatton did the right thing by retiring, he was a very good fighter, top class, no doubt about it.
